so i broke the skirt on one of my vtir pistons by dropping it and ive got a set of used type r pistons and a spare vtir one,,, now the question is do i go the type r ones or vtir ones....
the vtir ones are flat tops and weigh 100grams each less than the type r ones, the type r ones have a domed top for more compression. will the more compression weigh out the 100 grams per piston?
whats your take??!?!
